## AI summary
This pull request introduces infrastructure and code to support search
functionality for PowerToys settings, including a new search index
specification, a dedicated search library, and updates to the solution
configuration. The main changes are the addition of a spec describing
how settings should be indexed and navigated, the creation of a new
`Common.Search` project with a fuzz search implementation, and updates
to the solution file to include these new components.

**Settings Search Feature Implementation**

* Documentation:
* Added a detailed specification (`settings-search.md`) describing the
structure of PowerToys settings pages, how to index settings, navigation
logic, runtime search, result grouping, build-time indexing strategy,
and corner cases.

* New Search Library:
* Added the new `Common.Search` project to the solution, including its
project file and implementation of a fuzz search service
(`FuzzSearchService<T>`), match options, match results, and search
precision scoring.

* Solution Configuration:
* Updated `PowerToys.sln` to include `Common.Search` and
`Settings.UI.XamlIndexBuilder` projects, and configured their build
settings for various platforms and mapped project dependencies.

**Spell-check Dictionary Updates**

* Added new terms related to navigation and settings UI components (such
as `Navigatable`, `NavigatablePage`, `settingscard`, `Tru`, `tweakable`)
to the spell-check dictionary to support the new search and indexing
features.
